296ab7e544 It's inefficient to have place the exception tables (which contain the LSDA) 
into the __DATA section. At launch time, dyld has to update most of the section
to fix up the type info pointers. It's better to place it into the __TEXT
section and use pc-rel indirect pointer encodings. Similar to the personality
routine.

228252f981 Make a new X8632_MachoTargetObjectFile TLOF implementation whose 
getSymbolForDwarfGlobalReference is smart enough to know that it 
needs to register the stub it references with MachineModuleInfoMachO,
so that it gets emitted at the end of the file.

Move stub emission from X86ATTAsmPrinter::doFinalization to the
new X86ATTAsmPrinter::EmitEndOfAsmFile asmprinter hook.  The important
thing here is that EmitEndOfAsmFile is called *after* the ehframes are
emitted, so we get all the stubs.

This allows us to remove a gross hack from the asmprinter where it would
"just know" that it needed to output stubs for personality functions.
Now this is all driven from a consistent interface.

The testcase change is just reordering the expected output now that the
stubs come out after the ehframe instead of before.

This also unblocks other changes that Bill wants to make.

88d9839d07 Update malloc call creation code (AllocType is now the element type of the malloc, not the resulting type). 
In getMallocArraySize(), fix bug in the case that array size is the product of 2 constants.

Extend isArrayMalloc() and getMallocArraySize() to handle case where malloc is used as char array.

Ensure that ArraySize in LowerAllocations::runOnBasicBlock() is correct type.

Extend Instruction::isSafeToSpeculativelyExecute() to handle malloc calls.

Add verification for malloc calls.

This can be seen on CodeGen/Generic/2006-09-06-SwitchLowering.ll. But it's not known to cause any real regression (but I have added an assertion for it now).

6f65d79750 Add a new pass for doing late hoisting of floating-point and vector 
constants out of loops. These aren't covered by the regular LICM
pass, because in LLVM IR constants don't require separate
instructions. They're not always covered by the MachineLICM pass
either, because it doesn't know how to unfold folded constant-pool
loads. This is somewhat experimental at this point, and off by
default.
